Progressive pigmented purpuric dermatosis in skin of color: a dermoscopic and histopathological correlation

<p class="abstract"><strong>Background:</strong> Progressive pigmented purpuric dermatosis (PPPD) is a chronic cutaneous presents with petechiae, purpura on hyperpigmented yellowish-brown macules or patches. Diagnosis straight forward, sometimes may be challenging for the diagnosis. Dermoscopy non-invasive tool. It gives characteristic patterns in PPPD. However, dermoscopic descriptions skin of color are limited to case reports. Here, evaluation studied detail. </p><p class="abstract"><strong>Methods:</strong> was cross sectional observation study. Ethical clearance and written consent obtained. Patients type 4 5, attending dermatology clinic suspected lesions PPPD were selected serially. Handheld dermoscope used examination. Site examination considered as target area. Skin biopsy taken. Dermoscopic analysed features correlated histopathological changes.<strong></strong></p><p class="abstract"><strong>Results:</strong> Totally 30 patients 27 males 3 females enrolled. Schamberg’s disease commonest noted 21patients. Eczematoid, lichen aureus, lichenoid types seen 2 (6.7%) each. Hence, overall occurrence statistically significant (p=0.028). Commonest findings brown pigment network dots/globules. Least common included linear vessels bluish globules. Distorted 29 (96.7%).</p><p class="abstract"><strong>Conclusions:</strong> shows which network, red globules basic features. These correlate well changes. Yellowish-brown background prominently observed color. Larger studies recommended validate these differences.</p><p class="abstract"> </p>
